JOHN R. PHEENEY AND EUGENE OGDEN MAN, OF DENVER, COLORADO.

FOLDING CHAIR.

Application filed May 12, 1915.

To all whom it may concern:

Be it known that we, JOHN R. PHEE EY and EUGENE O. MAN, citizens of the Un1ted States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Folding Chairs; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in folding chairs, and has for its principal object to provide a frame for camp stools and the like, which may be readily folded so as to occupy a minimum amount of space. Y

Another object of the invention is to provide a frame of the above character which is capable of being modified so that it can be used in providing a cot or the like.

A further object of the invention is to provide a device of the above character which will readily fold into a compact bundle so that it may be easily transported.

Still another object of the invention is to provide a device which is strong and durable when in its extended position, and which is not liable to get out of order.

lVith these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which 2- Figure 1 is a perspective view partially broken away, illustrating our improved sup porting frame, as it would appear when in use, Fig. 2 is a perspective view of the frame, showing the same folded, Fig. 3 is an enlarged sectional View of the supporting hub, F ig.: 1 is a perspective view of the interior of the hub, Fig. 5 is a view partly broken away, illustrating one of the upper ends of one of the legs, Fig. 6 is a view illustrating the slidable leg and the relatively removable one, and Fig. 7 is a sectional view on the line 77 of Fig. 3.

Referring now to the drawings by characters of reference, the numeral 1 .designates as an entirety the hub of the device comprising the disks 2 and 3 which are connected at diametrically opposite points with the blocks or fillers 4:. These blocks or fillers are provided with the inclined faces 5, which faces are relatively forty-five degrees with relation to the vertlcal. Suit- Specification of Letters Patent.

able filler blocks 6 are formed at diametrically opposite points upon the hub, and these filler blocks are located intermediate the blocks a, as clearly shown in Fig. 3. The faces of these blocks extend in planes parallel with the vertical axis of the hub. One of the disks, preferably the disk 2 is formed with a central rectangular opening 7, the use of which will appear as the description proceeds. Each of the disks 2 and 3 is formed with a plurality of openings 8 which aline and are designed to receive the pivot pins of the legs, which will be more fully hereinafter described.

Extending through the openings 8 are the pivot pins 9, and are arranged in sets so that the pivot pins 9 on one side connect the blocks 10 and 11, and hold the blocks 10 and 11 in operative position, and the pivot pins 9 on the opposite side, hold the blocks 12 and 13 in operative position. Each of these blocks is rectangular in cross section, and is formed with an axial bore for the reception of the legs, which will be more fully hereinafter described. The blocks 10 and 12 are provided with bores relatively larger than the bore of the blocks 11 and 13, and are designed to receive the tubular legs 1 1 which are provided near their upper ends with apertures 15 for the reception of the bolts or rivets 16 by means of which the connecting elements 17 are pivotally mounted on the legs. The lower blocks 11 and 13 are provided with axial bores which are of a size suflicient to permit the legs 18' to slide therethrough and these legs are provided at their lower ends with suitable plugs 19 terminating in the enlargements 20, which are formed of rubber or a suitable material to provide feet for the device. Secured to the plugs 19 and extending upwardly through the tubular legs 18, are the springs 21 which extend through the openings in the blocks 10 and 11 and 12 and 13, and are connected at their upper ends to the pins 16 heretofore'referred to. It will thus be seen that the blocks 10 and 11 will be resiliently connected as will the blocks 12 and 13.

It will be seen that when the blocks 10 and 11 swing so that the legs 14 and 18 aline,

' held against movement.

23, illustrated in Fig. 4, and these bars are hinged on the disk 2 of the hub. A suitable rectangular extension 24 is riveted or otherwise secured, as at 25, to each. of the bars 22, and these extensions 24: are of a size sufiicient to fit within the rectangular opening 7 in each of the disks 2. It will thus be seen that when the bars 22 lie parallel to the disk 2, the rectangular extension 24 projects parallel with relation to the base of the disk, and when the bars 22 are swung outwardly on their pivots 23 so that they extend perpendicular to the disks 2, it will be evident that the rectangular extensions 24 will project into the openings 7 and engage the ends of the blocks 10, 11, 12 and 13, thereby holding the same in a position shown in Fig. 3. The meeting ends of the bars 22 are pivoted together, as at 26, as clearly shown in Fig. 1, and each of these bars is provided adjacent its pivoted end with a suitable longitudinally extending slot 27 for the reception of the hook end of the brace rod 28, the opposite end of which is pivoted to one of the disks 2, as at 29. Suitable notches are formed in the adjacent ends of the bars 22 and communicate with the slots 27, and these notches are arranged to engage the angular extensions on the auxiliary braces 28, to hold the device in its assembled position.

In order to support the seat 30 on the frame constructed as previously described, the pivotally connected bars 31 are provided and have secured to their ends the connections 32 which extend through suitable apertures formed in the connectors 17 hereinbefore referred to. The lateral edges of the seat 30 are provided with the rings 33, which surround the bars 31 and provide connection by means of which the seat is supported in extended position between the bars.

It will be apparent from the foregoing that in use, when the device is in its folded position, it will be evident that the legs 18 will he slid into the legs 14 and the bars 22 and 31 will be folded on their central pivots so that they will lie parallel to the legs 14. Assuming that it is desired to unfold the device and place the same in condition for use, the legs 18 are withdrawn from their position in the legs 14 and are then swung on the pivots 9 so that they asume the position illustrated in Figs. 1 and 3. The bar 22 is then swung on its central pivot so that the extensions 24 project into the openings 7 in the disks 2 and in this position it will be evident that the blocks 10, 11, 12 and 13 will be The seat 30 may then be placed in position, and it will be evident that a substantial and durable stool is provided which is of particularly light construction. The bars 2 are held in their extended positions by means of the brace rods 28 which engage behind the notches in the bars 22, and it will thus be seen that lateral movement of the whole is prevented.

In order to fold the device, the bar 22 is first swung upwardly on the pivot 26 and this will release the blocks 10, 11, 12 and 13, thereby permitting them to swing on their pivots 9, so that the legs 18'will aline with the openings in the legs 11 and the spring 21 therein will draw the legs 18 into the legs 14:, thus folding the device.

lVhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claims.

What is claimed is 1. A folding-stool of the character described, including a pair of hubs, means holding the hubs in spaced relation, blocks pivoted in the hubs, tubular legs secured in one set of blocks, cylindrical legs telescoping into the tubular legs when the device is in its folded position, and means to pull the cylindrical legs into the tubular legs when they are in alinement.

2. A folding stool of the character described, including a pair of hubs, means holding the hubs in operative position, legs carried by the hubs, and brace rods cooperating with the hub holding means in holding the hubs in operative position.

3. A folding stool of the character described, including a pair of hubs, means holding the hubs in operative position, telescoping legs carried by the hubs, and brace rods cooperating with the hub holding means in holding the hubs in operative position.

4. A folding stool of the character described comprising a pair of hubs, means holding the hubs rigidly in spaced relation, two sets of telescopic legs pivoted in each hub, springs connecting each set of legs to cause the same to telescope when in alinement, and rectangular extensions on the hub spacing means to hold the legs out of alinement when the stool is in its unfolded posi tion.

In testimony whereof we aflix our signatures in presence of two witnesses.
